Experimental Study on the Torsional Behavior of RC Composite Core Walls with Steel Tube-Reinforced Concrete Columns and Concealed Steel Trusses Subjected to the Combined Action of Multi-Directional Stresses

Abstract:

An experimental study on the torsional behavior of two 1/6 scale core walls: one reinforced concrete core wall with concealed steel trusses and steel tube-reinforced concrete columns, and one normal reinforced concrete core wall, was carried out under eccentric horizontal cyclic loading. The torsional load-bearing capacity, torsional angle ductility, torsional hysteresis characteristics, torsional stiffness and its deterioration process, torsional energy dissipation and damage characteristics of the two specimens are herein discussed. Results show that the torsional performance of RC core walls can be improved by embedding the concealed steel trusses in the walls and setting the steel tube-reinforced concrete columns as boundary-columns.
